JOHN GEORGE SCHWARTZ, OF NEVI YORK, N. Y.

SAFET Y AUTOMOBILE-LOCK.

To all vii/ mm it may concern:

Be it known that 1, JOHN G. SCHWARTZ, a citizen of the United States,residing at New York city, in the county of Bronx and State of New York,have invented certain new and useful Improvements in SafetyAutomobile-Locks; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to new and useful improvements in safetyautomobile locks, and has for one of its objects the provision of meansadapted to control both the fuel and ignition to the engine of anautomobile so that both may be entirely out off when desired to lock theautomobile against theft.

Another object ofthis invention is the provision of a self closing valvebetween the carbureter and intake manifold of the engine and which isheldopen by the insertion of a key in a look so that when said key isremoved the supply of fuel will be automatically cut off to the engine.

A further object of this invention is the provision of a connectionbetween the lock and the switch of the ignition system so that onactuation of the lock to permit fuel to the engine, the switch isautomatically closed to render the ignition system operative and whichswitch is opened when the key is removed for closing or cutting off thefuel to said engine.

A still further object of this invention is the provision of a safetyautomobile lock of the above stated character which shall be simple,durable and'efiicient and which may be manufactured and sold at acomparatively low cost.

With these and other objects in view as will. become more apparent asthe description proceeds, the invention consists in certain novelfeatures of construction, combination and arrangement of parts as willbe hereinafter fully describedand claimed.

For a complete understanding of my invention reference is to be had tothe following description and accompanying drawings, in which:

Figure 1 is a side elevation, illustrating a lock constructed inaccordance with my invention and showing it applied to an automobile andits engine,

Fig. 2 is a fragmentary view, illustrating Serial No. 3 1,652.

" tween the lock and switch,

Fig. 6 is a sectional view illustrating the lock,

Fig. 7 is a sectional view, taken on the line 77 of Fig. 6. v

Referring in detail to the drawings, the numeral 1 indicates anautomobile having the usual internal combustion engine that is providedwith an intake manifold 3 connected to a carburetor An auxiliary housing5 is interposed between the carbureter and the intake manifold and isprovided with oppositely disposed ears on each. end that are detachablysecured to the'intake manifold and the carburetor. A shaft 7 isjournaled in the housing 5 and has secured thereto a butterfly valve 8to which is secured oppositely extendin coiled springs 9 that have theirends secured to the housing 5 for normally urging the butterfly valve 8into engagement with the wall of the housing for the purpose of cuttingoff the fuel from the carbureter to the intake manifold. An arm 10 isconnected to the valve and has detachably connectedthereto one end of arod 11 by a coupling 1-2 which pivotally connects said rod to the arm aswell as permitting adjustment of said rod in relation to the arm. Therod 11 extends outwardly of the housing 5 and through a casing 12secured to said housing 5 and provided with an enlarged chamber 13 atits end and in which is pivotally mounted a bell crank lever 14, one armof which is pivoted to the end of the rod 11 while its other arm ispivoted to one end of'a rod 15. The rod 15 extends through a verticalcasing 16 which has communication with a lock housing 17 that is firmlysecured to the instrument board 18 of the automobile 1. A bell cranklever 19 has one of its arms pivoted to the upper end of the rod 15 andis secured to and operated by a lock 20 mounted in the housing 17. Thehousing 17 has a lateral branch on which is located the ignition switch22 consisting of a pivoted arm 23 adapted to be Specification of LettersPatent. Fatented Aug. 24:, 192 9.

moved into engagement with a contact 2% for completing an electriccircuit to the engine.

A rod is pivoted to the switch arm 28 and to the other arm of the bellcrank lever 19, thus it will be seen that when the device is unlockedthe butterfly valve 8 is moved to an open position permitting the fuelto enter the engine and simultaneouslyclosing the switch 22 of theignition system. As soon as the key is removed from the lock, thesprings 9 automatically close the valve 8 and opens the switch 22 thuspreventing the starting oi the engine until the lock is actuated by thecorrect key. The lock 20 consists of a casing 26 that rotatably supportsa key barrel 2? provided with a keyhole 28 adapted to receive the key 29for actuating the tumblers 30 that in turn operate tumblers 31 so as tofree the barrel 27 and permit rotation thereof by the turning of thekey. After the barrel has been rotated the key is pushed farther intothe keyhole and engages a spring pressed pin 32 causing the same toenter a recess 34: which holds the barrel against reverse rotation untilthe key is partially withdrawn from the keyhole whence the valve 8 isfree to move into closed position by the springs 9. The bell crank lever19 is fixed to the barrel for rotation or oscillatory movementtherewith.

lVhile I have shown and described the preferred embodiment of myinvention, it

ing valve in said auxiliary housing, a lock I in said lock housing, aseries of rods and bell crank levers in said casing for connecting thevalve to the lock, and means connecting the lock to the switch of anignition system.

2. An automobile lock comprising an auX- iliary housing, a lock housingreceiving the switch of an ignition system, a lock in said lock housing,a casing connecting said housings, a selfclosing valve in said auxiliaryhousing, bell crank levers and rods in said casing for connecting thevalve to the lock, and a rod connecting one of the bell crank levers tothe switch for causing simultaneous actuation of the switch with that ofthe valve.

In testimony whereof I afiix my signature in presence of two witnesses.
